Procurement Notes

Verify silicon revision level before procurement; this document covers revision 3.x silicon and later (orderable part numbers ending in A or B). Confirm compatibility with existing designs referencing earlier silicon revisions if applicable. Ensure power sequencing adheres to specified requirements to avoid excessive current draw during startup.

Selection Notes

Select this component for applications requiring high integration of networking and processing functions. Consider the specific I/O voltage requirements for DDR and Ethernet interfaces. Evaluate thermal dissipation needs based on operating frequency and load conditions. Verify software compatibility with existing Power Architecture implementations.

Part Context

The MPC8347EA is part of the PowerQUICC II Pro family, designed as a next-generation upgrade to the PowerQUICC II series. It builds upon the e300 SoC platform, offering enhanced performance and additional peripherals compared to previous generations. This processor targets demanding communication and embedded applications requiring robust connectivity and security features.

Replacement Considerations

For earlier silicon revisions (revision 1.1 and prior), refer to the MPC8347E datasheet. Cross-referencing with other members of the MPC83xx family may be necessary depending on specific peripheral requirements such as PCIe or SATA availability.
